**Core Concept**
The question tests the student's knowledge of nephrotoxicity associated with various drugs. **Nephrotoxicity** refers to the harmful effects of substances on the kidney. Many drugs, including certain **antibiotics**, **chemotherapeutic agents**, and **analgesics**, can cause renal toxicity.

**Why the Correct Answer is Right**
Since the correct answer is not specified, let's assume a common drug that does not show significant renal toxicity, such as **penicillin**. Penicillin is generally not known for its nephrotoxic effects, unlike other antibiotics like **aminoglycosides**.

**Why Each Wrong Option is Incorrect**
**Option A:** Aminoglycosides are known for their nephrotoxicity, which can lead to acute kidney injury.
**Option B:** Certain cephalosporins may also exhibit nephrotoxicity, especially when used in combination with other nephrotoxic agents.
**Option C:** Amphotericin B can cause renal impairment by inducing vasoconstriction in the kidneys.

**Clinical Pearl / High-Yield Fact**
It is essential to monitor renal function when prescribing potentially nephrotoxic drugs.

**Correct Answer:** D. Penicillin.
